HQSE-COUPLING.

To all whom it may concern.'

Be it known that I,`,M1CHAEL P. EAGAN, a citizen of the United States,residing at the city of Newport, county of Newport, and State of RhodeIsland, have invented certain new and useful Improvements in Hose-Couplings, of which `the following is a speciiication.

rIuhe object of my invention is to provide a hose-coupling which issimple in construction and effective in operation; and it consists oftwo members, one of which carries a locking-pin and also means toprevent a leakage of water after both members are coupled together.

In the accompanying sheet of drawings, Figure l represents a sideelevation of the male member of my improved hose-coupling, Fig. 2 is aside elevation of the female member. Fig. 3 is a central longitudinalsectional view illustrating the members as coupled together, and, F ig.4 is a cross sectional View of the female member, taken in line of Fig.2, showing the locking-pin and packing-ring as carried by said member.

Like reference characters indicate like parts throughout the views.

My improved hose-coupling comprises a male member a,, a female member b;aspringpressed locking-pin c and packing-ring d, the two latter partsbeing carried by saidY female member. The members a and b are of equallength and cast in tubular form. The male member c, has a centralannular flan e a3, to the rear end of which it is formed wit screwthreads c2. To the front of flange a3, the male member is formed with anannular enlarged portion a, a similar portion al, of less `diameter thana6, and connected to the latter 40 b y an annular beveled portion a7.Thus as shown in Fig. 3, when the male and female members are properlypositioned with respect to one another a tight joint is formed. Theouter end of the head al of the member a is beveled, as at a4, and nextto this beveled portion in said member is formed a circumferentialgroove a5. The female member?) has a head b1 respectively, and thismember has an annular flange b3 formed at its outer end, and anotherannular flange ?)4 formed at a point between 4the head b1 and threadedportion b2. Each of the -flanges b3, b4 has its surface knurled to gripupon in screwing the threaded portion of the member b within the`hosepipe-connection el.

and a screw-threaded portion b2 Patented .april 7, 11906. 'Serial No.358,998.

members a and b are of equal size and correspond to the inner diameterof the pipe-connections e and e1.

The head b1 of the member t is bored concentric to and of llargerdiameter than its bore f, to receive snugly therethrough the headv a,1of the/.member a, and this larger bore i'n the head b1, designated byreference character e5 in Fig. 3 terminates with a recess t thatsurrounds the inner portion of the iiange t of said member b. In therecess be, formed in the head of the member b, is securely mounted therubber packing-ring d, which is substantially square-shape in crosssection and whose inner diametrical portion projects close tothe bore fin said member. A contractile flat spring h partially surrounds the headof the member b and has one end secured thereto by a screw i, andintermediate the length of said spring is made fast an angularlydisposed pin c, which enters through a circular opening enlarged at itsbottom and formed in the wall of said head, in the manner shown in Figs.3 and 4. The free end of this spring it is curved slightly outward, asat h1, to permit of lifting inner or closed position on the member b.'

When the head of the member a is forced within the member b its beveledportion a4 causes the in c to move out from the chamber of the liead b1until acted upon, by the spring h, to iind its position in the groove a5of said member a.

Prior to the pin c lookin both members together as described, the eveledportion a4 will have entered within and compressed the packing-ring d,in the manner shown in Fig. 3, and thus sealing the coupling againstleakage of steam, air, or water.

By my construction and arrangement of parts, l form a device which canbe quickly coupled together and disconnected; a device which can be usedto advantage for connecing all flexible pipes, such as boiler-hose,airbrake-liose, iire-hose, and the like, and at the same time a devicethat is simple, durable,

` and inexpensive to manufacture.

What claim and desire to secure by Letters-Patent, is`

the pin c from its Y In a hose coupling, a male member having a centraloutwardly projecting annular flange to engage the hose end, an annularenlarged portion to the front of said flange, a second annular portionspaced from said first portion and of less diameter than the latter, abeveled annular connecting portion between said first named portions, abeveled outer end on said male member with a circumferential grooveformed between said outer end and said second named annular portion, afemale member having an interior opening shaped to receive said twoannular portions, and said beveled portion of the male member, anannular exterior flange at the outer end of said female member, a secondannular exterior flange spaced from the.

first and overlying the inner end of said interior opening of the femalemember, said female member having a circumferential recess wluch isformed in said second named exterior flange thereof, packing in saidrecess,

a flat contractile spring in' the form of the major part of a circlesecured to said female member in the space between said flanges thereof,and an angularly disposed pin carried by said spring at a pointdiametrically opposite its point of securenient, said female Witnesses:
